Camper battery maintainer

This unit works great at keeping my camper 12 volt battery topped off between outings. Perfect unit for this type of maintenance.

Edward W.
Nice unit

I didn’t pay anything for it so it’s well worth having. I have it hooked up to my riding lawnmower. Keeps the battery full charged even all winter. Easy to connect and disconnect. It’s saved me one battery so far

Todd P.

I needed to keep my battery on my rv charged. I hooked to the battery and we got weeks of no sun clouds morning to night and rain in December in SOUTH Florida. went to camper and the battery read full. I love this little solar panel.

Keith G.
Small and Powerful

I'm very happy with this solar panel. I bought it to charge a single 12V battery system at our ranch. It's nice and small and seems very solid. A fast test showed it producing 20.5V in tropical sun.They can be used for something else, like outdoor chair padding, and the box is good to line the trunk of your car.

Andrew D.
Love the performance

Just got this in and I was impressed by the build quality. I see many panels from this company getting good reviews. I'm going to be wiring that up and will report back on the findings but I can say this panel looks like it is solid and ready to work. It's heavy so you're not going to be backpacking with it but that's not why I bought it. This will be perfect for maintaining a battery at a campsite.
